 I can't explain why the .turd_openldap file was missing for you. It should
 have been there. Its presence just makes sure that MacPorts doesn't
 consider the directory empty and delete it. Deactivating and reactivating
 the port as suggested by the warning should have brought the file back.

 it actually used by anything if the user does not manually configure
 openldap?

 confirm though that openldap is only used if configured, or am I missing

 There is extensive prior discussion on this matter in the pull request
 that changed the openldap dependency from mandatory to a variant:

 https://github.com/macports/macports-ports/pull/2625

 Many argued that they did not need openldap support in gnupg2 and that it
 should be moved to a variant and that the variant should not be enabled by
 default. This would have the additional advantage that the gnupg2 port
 would become distributable. One of the maintainers of the port argued
 against the creation of the variant at all but eventually accepted the
 variant if it was enabled by default. The other maintainer did not
 comment.
